# hash_hmac_algos

(PHP 7 >= 7.2.0, PHP 8)

hash_hmac_algos — Return a list of registered hashing algorithms suitable for hash_hmac

### Beschreibung

hash_hmac_algos(): array

### Parameter-Liste

Diese Funktion besitzt keine Parameter.

### Rückgabewerte

Returns a numerically indexed array containing the list of supported hashing algorithms suitable for hash_hmac().

### Beispiele

Beispiel #1 hash_hmac_algos() example

`<?php
print_r(hash_hmac_algos());`

Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:

    Array
    (
        [0] => md2
        [1] => md4

    )

### Anmerkungen

> Hinweis:

> Before PHP 7.2.0 the only means to get a list of supported hash algorithms has been to call hash_algos() which also returns hash algorithms that are not suitable for hash_hmac().
